Last night I was able to get my Slash on a dirt track for the first time. Local track is running a Slash spec class - box stock. Any suspension adjustments can be made from what the stock equipment allows, and receiver changes, but nothing else. 6 cell NiMh/2s LiPo only.
I had never raced that track with any RC before, so I showed up a bit early to get some practice in. I ran about 15 minutes to get a feel for it, and it didn't take long to find it. The surface is red clay (all we have in this area..) that was dry when I arrived. They watered the track before the first heats began, to keep the dust down a little, but it was dried out pretty quick. 1/8th nitros ran ahead of us so the surface was loosened up before we got on.
Some pictures of the track are available here if you want an idea of what we were on.
The stock tires really worked well on dirt. You could break the rear end loose if you tried, so it was possible to powerslide around corners or to make a turn if you took it too wide. With five Slash's on the track, it was a great race. Running clean was the key, since it was hard to make up time with everyone running the same speeds. When more than two trucks came together there was some bumping and pushing going on, and the trucks took it well.
The Slash jumps great and it was pretty easy to get the right speed to hit the landings, and even if you came into a jump off-camber they seemed to fly true and land without much settling. Getting the right line to setup jumps gave an advantage as every second mattered. That's the beauty of spec class racing, it rewards clean driving. All of the races had some competition down the end in the top three spots, and it seemed like everyone had a great time.
If you have access to a track of any kind, I'd suggest setting up a Slash spec class and have a ball!
